Climatological normals for Wuhan in late April show average maximums consistently in the 22-25°C range. Historical data for April 29 corroborates this, with max temps rarely dipping below 20°C in the past decade. Given the strong solar insolation and typical late-spring synoptic patterns favoring thermal advection, 18°C represents an extremely low threshold. Boundary layer heating will easily push temperatures well past this mark. 95% YES — invalid if a significant cold air mass advection disrupts typical spring warming.
